A
Call it a day
Stop working on something
Get out of hand
Get out of control
Hit the sack
Go to sleep
Under the weather
Sick
We'll cross that bridge when we get there
Let's not talk about that problem right now
Costs an arm and a leg
Very expensive
Beat around the bush
Avoid saying what you mean, usually because it is uncomfortable
Time flies when you're having fun
You don't notice how long something lasts when it's fun
You can say that again
That's true, I agree
Don't count your chickens before they hatch
Don't count on something good happening until it's happened.
Go back to the drawing board
Start over
Don't cry over spilt milk
There's no reason to complain about something that can't be fixed
Don't put all your eggs in one basket
What you're doing is too risky
A blessing in disguise
A good thing that seemed bad at first
Wrap your head around something
Understand something complicated
Give someone the benefit of the doubt
Trust what someone says
Rain on someone's parade
To spoil something
Slow and steady wins the race
Reliability is more important than speed
The elephant in the room
The big issue, the problem people are avoiding
Like riding a bicycle
Something you never forget how to do
Fortune favours the bold
Take risks
I love her to death!
To care for someone (something) very strongly
Take a rain check
Postpone a plan
The devil is in the details
It looks good from a distance, but when you look closer, there are problems
Throw caution to the wind
Take a risk
You can't make an omelet without breaking some eggs
There's always a cost to doing something
Weather the storm
Go through something difficult
There are clouds on the horizon
Trouble is coming
Kill two birds with one stone
Get two things done with a single action
He has bigger fish to fry
He has bigger things to take care of than what we are talking about now
